Explain.
- The heat conducts through the shape below. The temperature of the right face is 93 °C, while the left faceis at 23 °C. If the top and bottom faces are completely insulated, and the thermal conductivity of thematerial decreases with decreasing temperature, sketch the temperature profile inside the plate.1. The boiling temperature of water is 100 °C. If you put boiling water in a mugplaced at the table top, you observed that after some time the water cools down,decreasing the temperature of water in the mug. Why is this so? Explain using theZeroth Law of Thermodynamics. What happens to objects when temperature increases? For instance, a jar cover an be removed by putting the cover in hot water. Why is this so?As shown in the figure, when the temperature was 20 ° C, a 0.5 mm gap was left. Just determine the approximate value (° C) of the temperature required to close the gap.
